Pharmaceutical formulations consist of active pharmaceutical ingredients (APIs) and excipients. Appropriate excipient selection is critical to the final quality of pharmaceutical products. When designing pharmaceutical preparations, the choice of excipients should not only consider the dosage form factors and excipient functions but also the interaction and compatibility between APIs and excipients. Therefore, during the research and development process of pharmaceutical preparations, comprehensive and reliable interaction studies are essential. These studies not only serve as a foundat…
About Tumor Suppressor Genes A tumor suppressor gene, also known as anti-onco gene, is an essential component of the body's defense against cancer. It usually facilitates apoptosis. With its absence, the human body will be functioning without its “brake” of cell proliferation. Cells are potent to go under abnormal growth processes and finally lead to tumor/cancer. Here are some key features and functions of tumor suppressor genes: Inhibition of Cell Growth:…
Microspheres are small spherical entities formed by dispersing or adsorbing drugs in a polymer matrix. The particle size is typically between 1 μm and 250 μm, and the largest can reach more than 800 μm. Microsphere technology is at the intersection of cutting-edge disciplines such as materials science, polymer technology, medical technology, and microelectronics. Once injected into the body, microspheres are gradually degraded in the body, allowing the drug to be released slowly at a certain rate, maintaining the drug concentration in the blood at the site of the lesion, thereby prolonging the half-life of the drug and achieving l…
Infectious diseases seriously threaten human health, and various infectious diseases may cause millions of severe cases and even death every year. Vaccination has been one of the most effective public health interventions in history, preventing millions of deaths worldwide.
